[HN] Antarctica: Ice shelves shrinking 'with no sign of recovery
A new study has found that almost half of Antarctica's ice shelves are shrinking. This could increase ice loss from glaciers and affect the ocean's ability to absorb carbon.

This is the best summary I could come up with:
Around 40% of Antarctica's ice shelves shrunk in the past 25 years, according to a new study published on Thursday.
Scientists found 68 of Antarctica's 162 ice shelves experienced a "statistically significant" reduction in mass between 1997 and 2021.
"We expected most ice shelves to go through cycles of rapid, but short-lived shrinking, then to regrow slowly," said Benjamin Davison, a research fellow at the University of Leeds, who was the lead author of the study published in Science Advances.
Another nine ice sheets saw smaller losses over the same period, while 29 gained mass and 62 did not change significantly.
This, in turn, slows its ability to transport vital nutrients, such as heat and carbon, to and from the polar ecosystem.
This is further evidence that Antarctica is changing because the climate is warming," said Anna Hogg, a University of Leeds professor who co-authored the study.
